Indigenous food crops refer to crops that have their origin in South Africa. Added to these crops are those that were introduced into the country and are now recognised as naturalised or traditional crops. These crops are produced and found growing in the country under various weather conditions with many found in the wild. They are divided into three categories; namely grains, vegetables and fruit.
Uses of indigenous food crops
- Leaves, corms and shoots are eaten as boiled, dried, sometimes roasted vegetables. These are also used as relish and in soups.
- Immature pods are dried or boiled while immature seeds are ground to make flour.
- Tubers are used as food substitutes for starch-enriched food such as rice and maize meal.
- Fruit types are eaten in ripened or dried form or nuts and can be processed into jam, jelly and juice
Advantages of growing indigenous crops
- Low input requirements
- Highly nutritious
- Resistant to drought, pests and diseases
- Better adapted to marginal areas than exotic crop

Indigenous grain crops
See also the “Other crops” and “Sorghum” chapters.
Indigenous grain crops can be defined as any crop yielding starch and protein-enriched seeds suitable for food. These crops are further subdivided into cereals (e.g. millet) and pulses (e.g. Bambara groundnut).
Indigenous fruit crops
Indigenous fruit crops are fruit types that are found diversely in the wild in South Africa. They are the seed-associated structures of certain plants that are sweet and edible in the raw state. Examples of fruit are marula, wild apricot, wild plum, raisin bush, sour plum.
Indigenous vegetable crops
Indigenous vegetable crops are defined as crops from which the tender leaves, stems and petioles are harvested and used in the preparation of vegetables. These crops are subdivided into roots/tubers (e.g. cassava, amadumbe, marama bean, living potato) and leafy (e.g. cleome, cowpea, amaranth, blackjack, Jews mallow). Table 1 provides the common and scientific names of a number of African vegetables found in South Africa along with the parts of the plants that can be consumed. [NOTE: Usually pumpkin is commercially produced for its fruit but because many Africans eat both the leaves, young and ripe fruit it is listed here as an African Vegetable.]

African vegetables and food security
The indigenous knowledge associated with African vegetables and their importance for the food security of many rural South Africans warrants further discussion. This is especially in light of food security activities emphasising food production and improved access to food in a country and region which is faced with two primary problems: water scarcity and the HIV/AIDS pandemic.
- Firstly, indigenous knowledge is eroding, because of its limited transfer between generations due to changing social systems, despite the significance of these plants to food security and livelihoods.
- Secondly, changes in population pressure on natural resources and a breakdown in the in-situ conservation strategies is starting to result in the deterioration of natural resources, including African vegetables and consequently the indigenous knowledge associated with them. This is despite the significant contribution to food security made by these plants and their associated knowledge, and the fact that existing exotic vegetable cultivars cannot make such a contribution in marginal areas as they need high inputs and optimal agroecological conditions.
- More attention needs to be paid to these plants and other indigenous food crops in order to increase their contribution to food security and the variety of ways in which this can be done from household consumption to commercialisation and value-adding. However, this process needs to be done with care and socio-cultural aspects need to be considered.

Local business environment
The indigenous food crop sector is faced with a number of challenges which hinder productivity and profitability:
- Shortage of seed and other propagating material. There is no formal seed supply system for many indigenous crops
- Increased decline in consumption and production. There is a shift among younger generations towards less nutritious foodstuffs due to lifestyle changes and assumptions about desirable eating habits.
- Lack of value-adding technologies. As a result indigenous crops are largely consumed unprocessed. The popular value addition is drying or processing into flour through pounding. Lack of processing technologies makes it difficult for the sector to cater for changing needs of consumers.
- Marketing problems. Both local and export markets are flooded by exotic crops making it difficult for the introduction of indigenous crops. As a result, indigenous crops remain largely crops of the small producers, consumed largely in areas where they are produced.
- Threatened species. Since a lot of the vegetables and fruit occur under natural vegetation, they face over-exploitation. Edible seeds and fruits of these crops are gathered from the wild and with current growing human populations, and increased numbers of range animals (which eat the foliage as well as seed) populations of these plants are at risk of over-exploitation. This may result in elimination of the species from the areas and this is mostly aggravated by the fact that no or little effort is done to cultivate these species.

“It is not an issue of increased agricultural production, but rather of allowing people who suffer from hunger to be in a better position to get, in whole or in part, their own food” (Former Italian Minister of Agriculture and Forestry Giani Allemanno)
Based on our experience, I firmly believe traditional African vegetables could be an important factor in strategies to alleviate food-shortages in rural and peri-urban settings and have useful applications following an ‘ecohealth’ approach (which takes into account human as well as ecosytem health).
According to the International Fund for Agricultural Development (IFAD), household food-security comprises not only food adequacy, but should also comply with nutrient and safety requirements as well as cultural preferences. In my view, reliable strategies to reduce food-insecurity in rural settings should acknowledge Africa’s indigenous food culture which is based on the utilisation of naturally-occurring food-plants and subsistence cropping of traditional vegetables.

International business environment
- One of the suggested measures to combat world hunger is to renew efforts to enhance the production and use of culturally appropriate, traditional and underutilised food crops.
- Modern agricultural research has concentrated on increasing the productivity of a few crops and breeds. As a result, a few crops have come to replace other, locally grown crops and there has been an enormous simplification of our agricultural systems. It has meant that our food security today depends on a very few species, which are traded globally and are available at very low prices.
- For small-scale farmers in marginal areas this has not been a positive development. Traditionally dependent on many different plant species for exchange and subsistence, many farmers have been drawn into agricultural economies based on cash cropping commodity crops with little regard for the complexities and multifunctionalities of existing agricultural systems that have developed over time and in close contact with local ecosystems. In many cases, rural communities have abandoned the cultivation of food crops and are now dependent on cash for their everyday needs. The tendency of world commodity prices to fluctuate violently over time makes this a very risky strategy. Over the past few years, for example, the prices of many commodities have fallen so low that they do not even compensate production costs. Farmers are unable to fill this income gap from their present agricultural system, and there is a growing realization that diversification of production is an urgent necessity.
- For other farmers, especially those living in areas unsuitable for the cultivation of improved varieties or commodity crops, agrobiodiversity is basic to survival. The more diversified their farming systems the greater the chance of self-sustainability and self-reliance. In such areas so-called underutilised species are particularly useful. They have been selected over time to withstand such stresses as drought and floods, and they can be produced in a sustainable way using available, low-cost, input practices. In many cases these species are also valuable sources of the micro-nutrients and vitamins needed to overcome the problem of “hidden hunger” – the lack of essential nutrients in diets consisting mainly of carbohydrate staples – which often affect the young and the elderly.
- Although useful and often nutritious, very little is known about these underutilised crops. Cultivation requirements, yield improvement potential and other properties are seldom investigated and rarely documented. Usually these crops have not been commercialised and little has been done to develop markets for them. It is difficult to find information on them and the traditional knowledge that used to be integrated into rural culture and handed down from generation to generation within local communities is disappearing rapidly with the “modernisation” of agricultural practices and the outward migration of young people.
- The displacement of local biodiversity is a major challenge not only for local food security but for the long-term sustainability of our global food system and the ecosystems that support it.
